BSYS 2060 - Database Assignment #2 Implementing the User Interface (REVISED) Task: Extend the "Pets-We-B" database to include the UI A retail Pet Store has asked you to design a database to capture the important aspects of their business data. In this assignment, you will build on the basic design to add tools to assist the user to interact with the database. Tables The store manager has asked if you can add two new tables to the database to help capture Invoice and Payment data. Each Sales record should have at least one Invoice associated with it, and each of these Invoices will have at least one Payment record. Invoices need to capture the Salel that the invoice is for the Date that the Invoice was created, and the Shipping Address data (which may or may not be the same as the Customer address). Payments need to capture the Invoicell the Date of the payment, the Amount of the payment, and the Type of payment (Cash, Cheque or Credit Card-you do NOT need to record any details of credit cards at this time.) The manager has also asked you to modify the Pets table to include a Final Price for each pet, by calculating the sales tax amount and adding it to the Price (assume a 12% tax rate for this field). The basic design of the database also needs to be extended to include user tools, like Forms and Reports. Forms There should be a basic form for editing or adding records to each of the Locations, Pets, Employees and Customers tables. There needs to be a form for recording basic Sales records, which should contain Lookup fields to select the required field values from the Locations, Pets, Employees and Customers tables. There should be a form for editing Sales and Invoices together. This form should show all of the Sale record data, and contain a Sub-form (in datasheet format) that allows the user to create Invoice records. The main Sales form should contain a calculation that COUNTS all the invoices for that Sale (there may be more than one). There should be a form for editing Invoice and Payment records. This form should show Invoice data and contain a Sub-form to display and allow the user to enter Payment records. The main Invoice form should contain a calculation to show the total of the Payment amounts associated with each Invoice. Reports The manager would like to see two Reports created. One report will show a list of all existing Sales records for the current year, organized by store Location, and sorted by Customer last name. You should show the total count of Sales records for each Location (Group Totals), and for the company overall (Grand Totals). The other report will show a list of unpaid Invoices, grouped by Customer last name, showing the total dollar amount outstanding for each customer. This report should also show the number of days each Invoice has gone unpaid (the difference between the invoice date and the current date, in days.) To test this report, you will need to create several Invoice records without creating any Payment records. In order to produce the forms and reports above, you may need to add queries to generate or calculate the required data. You may build any query you need to do this, although the final database you build should only contain useful queries, do not leave "testers" or experimental queries in the final design.
Answers
You are entrusted with expanding the "Pets-We-B" database to incorporate new tables, forms, and reports based on the given specifications.
Here is a step-by-step tutorial for setting up the database's user interface:
Redesign the database:
Create the tables Payment and Invoice.Create a foreign key in the Sales database to link each sales record to at least one invoice.Changes to the Pets Table:
The final price for each pet has been computed, therefore add a new column called "Final Price" to hold it.Add the sales tax amount (12% of the original price) to the Price column to determine the final price.Making forms
Make a form to modify or add records for each table (Vacations, Pets, Employees, and Customers).Make a form with lookup fields that allows users to choose data from associated tables for basic Sales records.Making Reports
Make a report that lists all of the current year's sales records, sorted by customer last name and organised by store location.
Ask questions:
To generate or calculate the data needed for forms and reports, create queries.You can use queries to get the information you need, such the total payment for each invoice or the number of sales records for each location.Completing the database
Any test or experiment-related queries that are not necessary for the final design should be removed.
Thus, this is the task asked in the scenario.

While the swing bridge is closing with a constant rotation of 0.5 rad/s, a man runs along the roadway at a constant speed of 5 ft/s relative to the roadway. Determine his velocity and acceleration at the instant d=15 ft
Answers
Thus, the man's velocity is 12.5 ft/s, and his acceleration is 7.5 ft/s^2.
The velocity of the man can be found using the relative velocity formula, which states that the velocity of an object relative to another is equal to the difference in their velocities. In this case, the velocity of the man relative to the bridge is: v_man/bridge = v_man/roadway - v_bridge/roadway Since the man is running at a constant speed of 5 ft/s relative to the roadway, we can plug that in and find the velocity of the bridge relative to the roadway, which is equal to the angular velocity times the radius of the bridge:
At the instant when d = 15 ft, the man's velocity and acceleration can be calculated as follows:
1. Angular velocity (ω) of the swing bridge is given as 0.5 rad/s.
2. Linear speed of the man relative to the roadway is given as 5 ft/s.
First, let's determine the man's linear velocity (V) taking into account both his speed relative to the roadway and the rotation of the bridge:
V = 5 ft/s (his speed) + (0.5 rad/s * 15 ft) (additional linear speed due to the bridge's rotation)
V = 5 ft/s + 7.5 ft/s = 12.5 ft/s
Now let's determine the man's acceleration (A) at the instant when d = 15 ft:
A = (0.5 rad/s^2 * 15 ft) (centripetal acceleration due to the bridge's rotation)
A = 7.5 ft/s^2
So, at the instant when d = 15 ft, the man's velocity is 12.5 ft/s, and his acceleration is 7.5 ft/s^2.

Derive the equations of motion for an airplane in descending gliding

angle φ below the horizon and that the aircraft is at a positive angle
of attack α. Show that these equations have one mathematical
degree of freedom and are the same as those obtained from Eqs.
(2.24) with T = 0 and γ = −φ
Answers
In descending gliding flight, an airplane experiences several forces and moments. The derived equation is ΣFx = W cos(γ + α) - L = 0.
To derive the equations of motion, let's start by drawing a free body diagram.
The diagram includes the following elements:
The aircraft, represented by a body with the longitudinal and vertical axes.
A coordinate system with an x-axis (horizontal) and a y-axis (vertical) that are fixed with respect to the Earth.
The velocity vector, which makes an angle φ (phi) below the horizon.
The weight force acting vertically downward.
The lift force perpendicular to the velocity vector.
The drag force opposite to the velocity vector.
The thrust force, assumed to be zero for gliding flight.
Now, let's consider the forces acting on the aircraft. The weight force can be decomposed into components: Wx in the x-direction and Wy in the y-direction.
The lift force can be decomposed into components: Lx in the x-direction and Ly in the y-direction.
The drag force can be decomposed into components: Dx in the x-direction and Dy in the y-direction.
In the vertical plane, the equations of motion are given by:
ΣFy = Wy + Ly - Dy - W = 0, where W is the weight of the aircraft.
ΣFx = Wx + Lx - Dx = 0.
We can rewrite these equations using trigonometric relationships:
ΣFy = W sin(γ + α) - D - W = 0, where γ is the glide path angle (equal to -φ in this case).
ΣFx = W cos(γ + α) - L = 0.
Since the aircraft is in gliding flight, the thrust force T is assumed to be zero.
These equations of motion have only one degree of freedom because the aircraft's motion is constrained to the vertical plane.

A centrifugal pump with a 700 mm diameter impeller runs at 1800 rev/min. The water enters without whirl, and α2 = 60o. The actual head produced by the pump is 17 m. Calculate the theoretical head and the hydraulic efficiency when V2 = 6 m/s.
Answers
The theoretical head of a pump refers to the maximum head that the pump can generate under ideal conditions, assuming that there are no losses due to friction, turbulence, or other inefficiencies.
To solve this problem, we can use the following equations for the theoretical head and hydraulic efficiency of a centrifugal pump:
Hth = (V2^2/2g) * [(cos α2 - cos α3) / (1 - D2/D1)^2]
ηh = (Hact / Hth) * 100%
where:
Hth is the theoretical head
V2 is the velocity of the fluid at the exit of the impeller
g is the acceleration due to gravity
α2 is the angle of the absolute velocity at the inlet of the impeller
α3 is the angle of the absolute velocity at the exit of the impeller
D1 is the diameter of the impeller at the inlet
D2 is the diameter of the impeller at the exit
Hact is the actual head produced by the pump
ηh is the hydraulic efficiency
Given:
D1 = 700 mm
N = 1800 rpm
α2 = 60 degrees
Hact = 17 m
V2 = 6 m/s
To find D2, we can use the following equation:
D2/D1 = sqrt(Hact / Hth)
where Hth is the theoretical head. Substituting the given values, we get:
D2/D1 = sqrt(17 / Hth)
To find Hth, we can rearrange the first equation and substitute the given values:
Hth = (V2^2/2g) * [(cos α2 - cos α3) / (1 - D2/D1)^2]
= (6^2/2*9.81) * [(cos 60 - cos α3) / (1 - (D2/D1)^2)]
To find α3, we can use the following equation:
tan α3 = tan α2 - (V2/U2)
where U2 is the peripheral velocity of the impeller. Substituting the given values, we get:
U2 = πD1N/60
= π0.71800/60
= 131.95 m/s
tan α3 = tan 60 - (6/131.95)
= 0.866 - 0.0454
= 0.8206
α3 = atan(0.8206)
= 39.69 degrees
Substituting α3 into the equation for Hth, we get:
Hth = (6^2/2*9.81) * [(cos 60 - cos 39.69) / (1 - (D2/D1)^2)]
To find D2/D1, we can rearrange the equation for D2/D1:
D2/D1 = sqrt(Hact / Hth)
= sqrt(17 / [(6^2/2*9.81) * [(cos 60 - cos 39.69) / (1 - (D2/D1)^2)]])
We can solve for D2/D1 using an iterative method or a graphical method. Using an iterative method, we can start with an initial guess for D2/D1, say 0.5, and substitute it into the equation above. We can then use the resulting value to calculate a new value for D2/D1, and continue the process until we get a value that is close enough to the true value.
After several iterations, we can find that D2/D1 is approximately 0.711. Substituting this into the equation for Hth, we get:
Hth = (6^2/2*9.81)

For those who run or work in a business that handles food, you understand the importance of food safety and regulation compliance as it pertains to not only to certification and licensing of a company, but also the life or death of those who consume the products. Because food safety is such an important issue, we want to ensure that all companies who work in the production, preparation, or processing of food have the tools and information they need to ensure they are in full compliance 100% of the time. One slip in food safety compliance could cost someone their health or life, and this information spreads mistrust in the general public toward the company who sold the product, and also the entire product across companies throughout an entire country and beyond. So how does each company working with food ensure they comply with each and every food safety regulation? Through excellent auditing tools.
Auditing in Food Safety Must Change
Auditing in food safety compliance is essential in ensuring that all regulations are being complied with. Most auditing practices for major companies are severely out of date. Many rely on several different forms, stacks of paperwork, and data stored on multiple different computers and databases. This is incredibly inefficient, as it can be easy to miss something when comparing one sheet to the next, and paper can easily be lost or destroyed. It is also time consuming for companies to share audits over separate computers and databases, as it must be passed down from one employee to the next. Technology has granted all food safety compliance managers a simple solution. Auditing apps are the new wave solutions for companies who want all of their data stored on one cloud database that is instantly accessible with real-time data for all employees. This means that no one ever gets left out of the loop, and no new information will fall through the cracks.

Discuss about the tool wear of cutting tool.
Answers
In the cutting tool industry, tool wear is an important concept. Wear of cutting tools refers to the loss of material from the cutting tool, mainly at the active cutting edges, as a result of mechanical action during machining operations.
The mechanical action includes cutting, rubbing, and sliding, as well as, in certain situations, adhesive and chemical wear. Wear on a cutting tool affects its sharpness, tool life, cutting quality, and machining efficiency.
Tool wear has a considerable effect on the cutting tool's productivity and quality. As a result, the study of tool wear and its causes is an essential research area in the machining industry.
The following are the types of tool wear that can occur during the machining process:
1. Adhesive Wear: It occurs when metal-to-metal contact causes metallic adhesion, resulting in the removal of the cutting tool's surface material. The adhesion is caused by the temperature rise at the cutting zone, as well as the cutting speed, feed rate, and depth of cut.
2. Abrasive Wear: It is caused by the presence of hard particles in the workpiece material or on the cutting tool's surface. As the tool passes over these hard particles, they cause the tool material to wear away. It can be seen as scratches or grooves on the tool's surface.
3. Chipping: It occurs when small pieces of tool material break off due to the extreme stress on the tool's cutting edge.
4. Thermal Wear: Thermal wear occurs when the cutting tool's temperature exceeds its maximum allowable limit. When a tool is heated beyond its limit, it loses its hardness and becomes too soft to cut material correctly.
5. Fracture Wear: It is caused by high stress on the cutting tool that results in its fracture. It can occur when the cutting tool's strength is exceeded or when a blunt tool is used to cut hard materials.

What must be used in series with a forward- biased diode to prevent damage due to excessive 15) current
Answers
Answer:
A resistor
Explanation:
A diode is an electrical device that allows current to pass through it only in one direction. When a diode is forward biased, it allows current to flow through it in direction but when it is reverse biased, it stops current from flowing through it.
The maximum forward current is the maximum current allowed to flow through the diode when conducting in the forward bias condition. If the maximum forward current is exceeded, it leads to heat which causes damage to the diode.
A resistor is conducted in series to the forward biased diode to limit the current flowing through it thereby ensuring that the current is below the maximum forward current.

TMI Systems, a company that customizes software for construction cost estimates, repaid a loan obtained 5 years ago at 10% per year simple interest. If the amount that TMI repaid was $140,000, calculate the principal of the loan
Answers
The principal of the loan that TMI Systems repaid was $90,000.
The formula to calculate the principal of a loan is P = L + I, where P is the principal, L is the loan amount, and I is the total interest paid over the duration of the loan.
In this case, we are given that the loan amount was 10% per year simple interest, which can be calculated by multiplying the principal by the interest rate (0.1) and the duration of the loan (5 years). Therefore, the total interest paid over the duration of the loan is P x 0.1 x 5 = $50,000.
We are also given the total amount repaid, which is the sum of the principal and the total interest paid. Therefore, we can calculate the principal by subtracting the total interest paid from the total amount repaid.
This gives us $140,000 - $50,000 = $90,000. As the principal must be a positive value, the principal of the loan is $90,000.

In an automated manufacturing process, three holes are drilled simultaneously in an aluminum block as shown. Each drill exerts a 50-N force and a 0.100-N. m couple on the block. Knowing that drill A rotates counterclockwise and drills B and C rotate clockwise (as observed from each drill), reduce the forces and couples exerted by the drills on the block to an equivalent wrench and determine (a) the resultant force R, (b) the pitch of the wrench, (c) the point where the wrench intersects the xz plane.
Answers
(a) The resultant force R is 150N,
(b) The pitch of the wrench is 15 N.m,
(c) The point where the wrench intersects the xz plane is at the origin in the xz plane.
How do we determine these values?To find the equivalent wrench, we need to find the vector sum of the forces and couples exerted by the three drills.
(a) The resultant force R can be found by adding the three forces vectorially. Since the forces are all in the same direction, we can add them scalarly:
R = F_A + F_B + F_C = 50 N + 50 N + 50 N = 150 N
(b) The pitch of the wrench can be found by finding the cross product of the resultant force and the couple:
pitch = R x M = (150 N) x (0.100 N.m) = 15 N.m
(c) The point where the wrench intersects the xz plane can be found by setting the y-component of the moment vector to zero:
M_y = 0
Since the moment vector is perpendicular to the xz-plane, we know that the point of intersection must lie on the xz-plane.
The equivalent wrench is a force of 150 N acting in the positive x-direction and a moment of 15 N.m around the y-axis. The point where the wrench intersects the xz plane is at the origin in the xz plane.

if a machine is rotating at 1800 rpm and synchronous speed is 1300 rpm determine if the machine is a generator or a motor by finding the slip.
Answers
Since the slip is negative (-0.3846), this indicates that the machine is operating as a generator, not a motor.
To determine whether the machine is a generator or a motor, we need to find the slip of the machine.
The formula for slip is:
Slip = (Synchronous speed - Actual speed) / Synchronous speed
In this case, the synchronous speed is 1300 rpm and the actual speed is 1800 rpm.
Slip = (1300 - 1800) / 1300
Slip = -0.38 or -38%
S = (Ns - Nr) / Ns
S = (1300 - 1800) / 1300
S = (-500) / 1300
S = -0.3846

This wired networking standard specifies the order in which data is sent through the network.
Select one:
a. Ethernet
b. WiMAX
c. LTE
d. TCP/IP
Answers
The wired networking standard that specifies the order in which data is sent through the network is Ethernet.
Ethernet is a widely used wired networking standard that defines the protocols and specifications for data transmission over a local area network (LAN). It specifies the order in which data is sent through the network by utilizing the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) algorithm.
The CSMA/CD algorithm ensures that multiple devices connected to an Ethernet network can share the same communication medium without interfering with each other. Before transmitting data, a device using Ethernet listens to the network to detect if it is clear to send data. If the network is busy, it waits for an opportune moment. Once the network is clear, the device sends the data, constantly monitoring for collisions. If a collision occurs (when two or more devices transmit data simultaneously), they stop transmitting, wait for a random period of time, and then retry.
By following this protocol, Ethernet ensures orderly and efficient data transmission within the network, minimizing collisions and maximizing data throughput. It has become the de facto standard for wired local area networks due to its reliability, scalability, and widespread adoption.
